Id New Specimens...

[Kirsch]

Please can someone help me out to ID some specimens...

[Fossildude19]

The first piece looks like modern barnacles, and the second one looks like wood - possibly petrified.

Third item I see nothing particularly fossily about - could we get more pictures of it from different angles?

Also where were these found?

Size of items?

Regards,

The first piece looks like modern barnacles,

Agreed. Looks very much like a modern clump of Megabalanus tintinnabulum.

The second piece looks like a chunk of driftwood (with a nice double knot right in the middle).

The last one is oddly gastropod (snail) looking but I'm sure that is probably just geology once again mimicking biology. Would be interesting to see a different view of this piece.

Were these collected from the beach in Mexico?

Cheers.

Thank you very much Tim, as for the first one I looked it up and you are right, it is a BARNACLE (CIRRIPEDIA) from the Mid-Cambrian. The second one, it is a Petrified Wood, but when I got it it only said Egypt 1500AC that's it. The third one, is about 2 cm long, and 1cm height. I´m pretty sure it´s a GASTROPOD, I think it's a LYMNAEA anyway let me take more pictures and ill show them to you, thanks again....

You are right Ken, I looked it up and it is what you say. As for the gastropod, I collected it from a beach in the Yucatan Peninsula. The Barnacle is from the Coast of Portugal. And the petrified wood was a gift but the only specification was: FOSSILIZED WOOD FROM 1500A.C. EGYPT, that's it....so im trying to get a little bit more out of it...thanks again you guys...

I would like to clarify that the barnacle cluster is modern, and that the wood is from the late Middle Ages, and is still wood (not turned to stone, or "petrified").

I hate to appear dogmatic concerning something I know so little about (invertebrates) but there is no way that is a mid-Cambrian barnacle.

Here is a link to a picture of the only known pre-Silurian barnacle (?) the mid-Cambiran Priscansermarinus barnetti

Hi everyone I am posting new pictures of the celaphod in different angles so it can help identify...

I am also posting what it seems to be a part of a coral, maybe someone expert in the field can tell me what it is... and another petrified snail (polished)

I'd really appreciate some help to ID these samples...thanks again...LK

Your 'cephalopod' may be a snail also; it does not show any chamber septa.

The coral (if a relatively modern skeleton and also collected from the Yucatan) would likely be Porites (either P. porites or P. furcata). Can't really help much with the gastropods. NOTE: the first one is a gastropod (snail) and not a cephalopod which is the class that contains such creatures as octopuses, squid, cuttlefishes, and the nautiloids (including the extant paper and chambered nautilus as well as the extinct belemnites and everybody's favorite, the ammonites).

The new (polished) one is quite striking and reminds me of a cone shell.

Cheers.

Thank you all for this helpful information.

The polished gastropod might be Actaeonella gigantea from the Cretaceous of Gosau, Austria. Can get the size of a fist. They are sold by the thousands as paperweights.

I think so too. It is probably from Austria. A second source is in Romania and these were traded by an Austrian dealer.

Who would have thought that a polished gastropod like that would be so easy to identify. The breadth of knowledge contained within the collective noggins on this forum amazes me some times.

Cheers.
